To all whom "It may'concem:

Be it known that I. FRANtlS J. Mav- BORGNE, a citizen of the United States, and a resident of New York city, in the county of New York and State of New York, have invented a certain new and useful improve-' ment. -in Mattress and Furniture Springs.

. of which the following is a specification.

The object of this invention is to preserve the form, outline and sha )9 of spring-inattresses, chair-seats and ii iholstered articles. and to preserve the life of the springs throughout the mattress. seat or upholstering: that is. in all s n'ing-lmrdered work, furniture'aml mattress. .-\s made heretofore, such art icles sooner or later get out of shape. at the edges in use. owingto lack of transverse stillness. and have to be made over or repaired with rephu-ement of many springs in order to restore them to pro )er form or outline and life. Another de.ect

' of such work heretofore has been the weariii) ing out of the lashing whereby the ratan is secured to the outer rows of springs thus releasing the. border springs; the ratan turns on the border springs. thus bringing the lashing under strains which break it in a short while.

According to the present invention, transverse stillness is secured by means of springs having reverse-coils in them. which springs have. reve|'se-coil.-; in them and which are secure-d to the ruian or cord running around the spring!mrdered work and also to some part; of the woodwork as well as to the usual coiled springs, if desired. 'ilu-se reversecoil springs may be arranged, by their shape, to give more or less resistance to both mward and downward pressures or to either.

it is observed that the new springs are equally applicable in original construction as well as in repairwork; that is, they may be used when the mattress. seat or upholstcring is made in the first instance, or they may be. put in place at any time thereafter as in repairing the same.

The invention is embodied in the springs illustrated in theaccompanying drawing. forming part hereof, in which- Figure l is a plan view: Fig. 2 is an eleation of the same; Fig. 3 is an elevation of the spring applied i a shelf A; Fig.4 is an elevation showing t spring attached to a. bar A" in a chair; Fig. 5 shows a loop;

t i 1 i i I and 4 which areumnected by the separators,

5, and the arms ti which are curved upward and outward and which have their ends formed into the lips or cradles 7 to receive.

the rutun or cord C. .The base .2 is attached to a slut A by staples s. and the cradles T and the arms (5 are secured to the ratan C by lashings I, of cord or other suitable material. 'lhe cradles T are formed by bending the wire-ends at about right angles, laterally, with the arms t3 and then about parallel thereto, and bending the arms (2 and their ends downwardly, as shown in Figs. 1 and 2, to receive the edge, as the ratan or cord C.-

The arrangement shown in Figs. 1 and 2 is the preferred form in respect of the cradle, since. the rntan cannot turn out of the cradle;

whereas. if the cradle is carried only to about the center of the ratan. as shown in Fi s. 3 and 4, the ratan is liable to twist over t \e end of the wire. get beneath the cradle and thus lead to the destruction of the outline of the. mattress or other spring-bordered article. The new springs may also be lashed to the usual border spring B (see Z). Or.

may be formed in the arms tand loops S the springs B be wound through them to connect them to said arms ti. with a saving of time in assembling. The springs B are omitted from Figs. 3 and 4, but it will be understood that they are. or may be, used there.

The ordinary springs 7 formed thereon for the. reception of the ratau lashings 7 being used to secure the spring and ratar. together, thereby prevent,- ing the ratan from twisting over the end of the spring. The stiffening springs have reverse coils, 3. 4. in each branch thereof, these coils being free to act as springs to any extent by twisting and unt-wisting. These springs l are used at the borders, all around the mattress or other spring-bordered part,

is may have cradles and are each disposed at substantially right a single i ,1 at

' is merely laid in place and is then lashed.

What] claim as new and desire to secure by Letters Patent of the United States is- 1. ln spring-mattresses and the like, a border. and a vertically-acting nesting spring for eoaction therewith, combined with a horizontallv and vertically act ng spring consisting 0 a U-shaped base for attachment to.thc framework, two arms, each provided with a pair of reverse coils, extending from said base, means for attaching said arms to said nesting spring, and means for attaching the extremities of said arms to said border.

2. ln spring-mattresses and the like, a border, and a vertically -actin nestin spring for eoactiortherewith, com iincd with a horizontally and vert-i ally acting spring consisting of a U-shaped base, for attachment to the framework, two arms each provided with a coil near said base and connectors extending upwardly from'said coils to points above and laterally away from said base and with coils at said points reversed as compared with the first-named eoils and said arms then continued upwardl and outwardlytof the mattress or the like) to the. border, means for securing said arms to said nesting springs, and means for securing the extremities of said arms to the border.

. 3. in spring mattresses and the like, a border and a vertically-acting nesting spring coat-ting therewith, combined with a horizontally and vertically acting spring consisting of a U-shaped base for attachment to the framework extending into two arms each provided with a pair of reverse coils and terminatin in cradles for receiving said border, am means for fastening said springs and bordertogether.

4. ln spring mattresses and the like, a sti tlening spring consisting of a single wire bent at its middle portion to form a U- shaped base. whereby it may be attached to a framework and the ends of the U-basc being continued upwardly and backwardly and then forwardly and horizontally and provided each with reverse coils, whereby the sprin may yield horizontally and vertically, and the ends thereof being formed into cradles for receiving the border or ratan.

5. in spring mattresses and the. like a stiti'ening spring consisting of a single wire bent at its middle portion to form a U- shaped base whereby the spring may be attached to a framework, the ends of the U- base being continued upwardly, rearwardly and then forwardly and horizontally and provided each with a pair of reverse coils in their rearwardly and forwardly parts and with loops in their horizontal parts, and the ends thereof being shaped for connection with the border or ratan.

Signed at New York in the county of New York and State of New York this ninth day of January. A. l). 1908.
